. The invention relates to cord bracelets for wrist watches and is moreparticularly directed to a novel and efficient slide whereby suchbracelets may be readily 'adj usted t-o properly fit the wrist of thewearer.

Cord bracelets are at present widely use to support wrist watches inposition, in lieu of usual straps or ribbons, but no satisfactory meansis known to the trade which will permit of the adjustment of suchbracelets to the wrist. Various devices have been suggested for thispurpose, but in every instance the structures have been complicated,expensive and unreliable and have not met with popular favor.

The primary object of the present invention is therefore to provide asimple, economical and reliable slide construction for the purposestated.

In practically carrying out the present invention, the bracelet ispreferably constructed from two cords. One of said cords is passedthrough the att-aching ring at one side of the watch and secured to onesection of a suitable clasp. The other cord is secured to the othersection of the clasp and from thence passes to and through a slideconstructed in accordance with the present invention, beyond which Vthecord is led through the attaching ring at the other side of the watchand then returned upon itselfV and anchored to said slide.

Generally speaking, the slide o f this invention, comprises twofundamental elements, namely, means to anchor one end of a cord thereto,and means to form ina portion of the cord intermediate its length, anoffset whereby the cord is bent or caused to be diverted from a straightpath, to the end that s'uliicient friction may be set u between the cordand the slide as will prec ude inadvertent slippage between them. f

In its preferred practical form, though not the exclusive one, theseends are economically accomplished by constructing the slide from twotubes, each having an interior diameter substantially equal to thediameter of the cord to be used therewith. These tubes arelongitudinally bent or curved and are secured 50 together side by sidein such relation that at one end of the slide said tubes will join orintersect to form a single or common outlet while at the other end oftheslide the outlets of the respective tubes will be independent of oneanother and placed side by side.

"Vith this arrangement one end of the cord can be introduced into one ofthe twin outlets and permanently anchored within the corresponding tube,while another portion of the cord canl be passed wholly through theother tube, so as to extend from the watch to the clasp.

It will be apparent, however, that the portion of the cord that passeswholly through the slide is caused, because of the longitudi- C nalcurvature of the tube through which it passes, to be diverted from astraight path or offset. Thus sufficient friction is produced betweenthe slide and cord to preclude inadvertent slipping of the cord throughthe slide, whereby the parts will maintain the desired adjustment. Theslide may, however, be manually shifted to `properly fit the bracelet tothe wrist. v

ttention is called to the fact that with the construction described, theslide will not subject the cord toV appreciable wear or distortion.There are no movable parts to get out of order and the structure is neatand pleasing in appearance. Moreover, this arrangement readilylendsitself to ornate ormentations to suit the most fa'stidious tastes.

Features of the invention, other than those specified, will be apparentfrom the hereinafter detailed description and claims, when read inconjunction with the accompanying drawings.

The accompanying drawing illust-rates different practical embodiments ofthe invention, but the constructions therein shown are to be understoodas illustrative, only, and not as defining the limits of the invention.

Figure l shows a bracelet embodying the present invention laid out flat.

Figure 2 is a central section through the slide illustrated in Figure l.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a view similar to Figure 2, but illustrating a modified.form of the invention.

Cil

Figure illustrates a further modified form of the invention inelevation. i

In said drawings,1 designates a wrist watch provided on its oppositesides with attaching rings 2 and 3, while the reference character 4designates aV suitable clasp which may be of any desired constructionand two detachable sections 5 and 6. The bracelet shown in Figure 1embodies two cords. Y One cord designated 7 is formed into a loop whichpasses through the ring 2 on one side of the watch, both ends of thecord being anchored in any suitable way to the section 5 of the clasp.The other cord which is designated S is secured at one of its ends tothe section 6 of the clasp, as at 9. From thence the cord is passedthrough the slide 10 of this invention and beyond the slide extends toand through the ring 3 of the watch, being thereafter returned uponitself and the same secured to the slide 10.

The slide 10 may partake of various forms, but Figures 1,2 and 3 showthat which is preferred. In these views, the slide is constructed fromtwo pieces of metal tubing 11 and 12 of substantially the same length.They are secured together at their opposite ends by soldering orotherwise and are longitudinally bent in opposite directionsintermediate their ends as best illustrated in Figure 2.

Both of these tubes have an inner diameter which is substantially equalto the diameter of the cord 8 and in securing the tubes together, theyare assembled as shown in Figure 2, so that at the left hand end of theslide in this ligure, both the tubes 11 and 12 will intersect or bejoined together in such manner as to form a single outlet 14. ln otherwords,

the tube 11 is butt-soldered to the side of the tube 12 so as to closethe end of the tube 11 to leave the end of the tube 12 open to provide asingle outlet 14. The opposite ends of the tubes are soldered togetherside by side, so as to leave twin outlets 15 and 1G corresponding to therespective tubes 11 and 12.

In associating the cord S with the slide which has been described, thefree end 8 of the cord Sis passed through the outlet 15 into theinterior of the tube 11 and there anchored in position in any suitableway as by passing the pin 17 through the tube and cord. rlhe other endof the cord is thereupon passed through the attaching ring 3 ofthe watchand after being returned upon itself is passed through the tube' 12 asshown in this ligure.

It will be noted that where the cord passes through the tube, it isoffset or diverted laterally from arstraight pathfand, accordingly, anytendency to pull` the cord through this tube 12 will result inpronounced friction because the cord lits fairly tight within the tube.It will be clear, however, that if it is desired to adjust the braceletby increasing or decreasing the distance between the clasp and the watch1, the slide may be manually moved by hand by imparting theretosuliicient force to overcome the friction between the cord 8 and thetube 12, but this friction is normally sufliciently great to effectuallypreclude slipping stantially aline with the direction of pull of thecords so that the cords will not wear at the outlets.

The structure shown in Figures 1 to 3 isV particularly adapted for thepurposes stated.V .The contour of the construction is symmetrical andreadily lends itself for employment as a backing for jewels or otherornamentation which it may be desirable to mount thereon. We may,however, construct the slide in other forms than that already describedand in Figures 4 and 5 two other constructions are illustrated. Here thetwo tubes 11 and 12Z1 are longitudinally curved, but are broughttogether at only one end of each, so as to form a substantially Y-shapedslide. The free end of the cord 8 is anchored within the tube 11a. whilethe intermediate portion of the cord passes unobstructedly through thetube 12L which is longitudinally bent to produce the friction desired.

Another modified form of construction is illustrated in Figure 5. Herethe slide is y self and passed through the ring 20, the rings 21 and thering 19 in succession.

l/Vhere this returned portion of the cord partially embraces the core18, it is diverted from a straight path or offset for the purpose ofproducing suiicient friction with the core to preclude inadvertentshifting of the cord relative to the slide. Y

The foregoing different slide constructions rco are illustrative of'different ways of adjusting l the cord of thev bracelet of thecharacter under consideration, but, in practice, it is found that thestructure of Figures 1 and 2 is the most desirable, although notexclusive. Y The foregoing detailed description shows illustrative formsof the present invention, but the'invention is to be understood as fullycommensurate with the appended claims.

Having thus fully described the invention, what we claim as new anddesire to secure by Letters Patent is:

1. A slide for cord'wrist watch bracelets comprising a body portionhaving a passage extending for substantially the full length of the bodyand throughwhich a cord mayeX- tend, said passage being shaped to divertor offset the cord from a straight path and of a size to snugly embracethe cord to thereby preclude inadvertent movement of the cord throughsaid passage, and means for anchoring one free end of the cord to thebody por7. tion.

2. A slide for cord wrist watch bracelets comprising a tubular bodyhaving therein two longitudinally curved passages through one of which acord is adapted to be passed and into the other of which the free end ofthe cord may be inserted, said passages being of a size to snuglyembrace the cord, and means to anchor the free end of the cord withinsaid body.

3. A slide for cor'd wrist watch bracelets comprising a tubular bodyhaving therein two longitudinally curved passages, one of which extendsfor the full length of the body l and is open at both ends, and theother of which extends from one end of the body and abuts the wall ofthe other passage, whereby the body has one inlet at one end and twoinlets at the other end, said passages being of a diameter to snuglyembrace a cord adapted to be passed through one of said passages and oneof its free ends inserted into vthe other passage, and means to anchorsaid free en'd of the cord in the latter passage.

4. A slide for cord Wrist watch bracelets comprising a tubular bodyhaving therein two longitudinally, oppositely curved passages, one ofwhich extends for the full length of the body and is open at both ends,and the other of which extends from one end of the body and abuts thewall of the other passage adjacent the other en'd of the body, wherebythe body has one inlet at one end and two inlets at the other end, saidpassages being of a diameter to snugly embrace a cord adapted to bepassed through one of said passages and one of its free ends insertedinto the other passage, and means to anchor said free end of the cord inthe latter passage.

In testimony whereof We have signed the foregoing specication.
